Abstract
During the deposition of a catalytic component on a carrier, the position of the liquid level of a slurry containing the catalytic component is controlled with high accuracy and the adhesion of the slurry to the lateral face of the carrier is prevented. In the deposition of the liquid substance on the carrier by the introduction of the liquid substance into the carrier from the bottom face thereof, the liquid level near the top face of the carrier is detected by an image-processing sensor.
